Abstract

We consider a relativistic model of quark confinement incorporating both a linear large-distance potential and Coulomb-like short-distance potential. Special emphasis is placed upon predictions for leptonic decay widths and the

2 s - 1 p

radiative transition of the charmonium model. We find that relativistic enhancement of the former force one to a situation in which the

2 s - 1 p

transition width is large.
